This invention relates to improvements in life preserving suits. r V p The object of the'invention is to provide asuitable suit to protect a person while'in the water, and toarrange the parts in a manner to permit ready breathing if the Water should be rough and dash over the suit.

provide special means between the jacket and pants of the suit to permit ready and quick action in securing the suit on the body of the wearer.

A still further object of the invention is to providefispecific means for permitting breathing: of'the wearer of the suit, such The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described-and particularly pointed out in the claims.

a jacket 2,. and a helmet .3, the helmet and jacket being connected by an accordion-like collar 4.

The body of the helmet is metal, and the 5-0 the helmet is a horizontal housing 8, and

A further object of the invention is to The suit is composed of a pair of pants 1,

communicating with the outer end thereof are lateral compartments 9-9, the outer walls of which incline upwardly and tor-" wardly; Connected to the open ends of the compartments are open work chambers 10+ 10,- each comprising an end frame-11, and a wire cage extending fromthe frame, packing beinginterposed between the compartments and the chambers'. The frames are connected to the open ends of the compartments and are formed with valve seats 12' against which ball valves 13,-confined in thechambers, are adapted to engage, the balls being confined between the valve seats and the ends of the chambers.

At the upper edge of the pants is a floatable band 13 and at the lower edge of the jacket is alike band-14:. Each band has a wood core 15, suitably covered as at 16.

Meansare provided to conveniently con nect the jacket andpantswhen the suit is applied. Secured to and extending from the upper part of the jacket band at intervals, are brackets'lS, and pivoted to these brackets are sleeves 19, provided with lateral slots 20, and end flanges 21, springs 21 fitting over the sleeves and confined by the flanges'21. Operating in the sleeves are rods 22, the upper ends of which have lateral extensions 23, which engage with the upper ends of the springs, while the lower ends of the rods depend below the sleeves and are provided with lateral extensions 2e.

Secured to and extending from the lower edge of the band 13, are brackets 25, having fingers 26 adapted to engage with the lateral extensions 24 on the rods.

Having thus described my invention, what I claim is 1. In a life-saving suit, the combination of a pair of pants, a floatable band at the upper end of the pants, a jacket, a floatable band at the lower end of the jacket, the aforesaid bands engaging each other, means for'securing the bands together, a helmet, flexible means connecting the helmet and jacket, a housing extending from and communicating with the helmet, a compartment extending from and communicating with the housing, said compartment having a horizontal chamber, packing between each chamber and the compartment, and a ball valve in the chamber adapted to gravitate therein toward and from the packing under the influence of the waves when the suit is in use to alternately close the compartment against'the admission of water and permit the admission of air. i

2. In a life saving suit, the combination of a pair of pants, a floatable band at the upper end of the pants, a jacket, a floatable band at the lower end of the jacket, the aforesaid bands engaging each other, means for securing the hands together, a helmet, flexible means connecting the helmet and jacket, a housing extending fromand communicating with the helmet, lateral compartments extending from and connecting with the housing, a horizontal chamber commumcatmg with and extending from each compartment, a valve seat between each chamber and the compartment, a ball valve located in each chamber adapted to cooperate with the seats to closethe admission of water to the housing when the helmet is tilted, a mouth opening in the front of the helmet, and a door closing the mouth open mg. i r

'3. In a life saving suit, the combination of a pair of pants, a floatable loand at the upper end of the pants, a jacket, a floatalole band at the lower end of the jacket, the aforesaid bands engaging each-other, means for securing the hands together, a helmet,

flexible means connecting the helmet and jacket, a housing extending from the rear of the helmet and communicating with same, upper and lower lateral compartments extending from and communicating with the housing, the rear wall of each lateral compartment being inclined from the housing in a direction toward the helmet,'the front of each lateral compartment having a flexible valve seat, an elongated chamber extending from each valve seat toward the helmet, and a ball valve operable in each elongated chamber and adapted to contact with the flexible valve seat to close the housing against ad-' mission of water when the suit is in use.

4. In a life-saving suit, the combination of apair of pants, a floatable band at the upper part of the pants including a wood .core and resilient lining, a jacket, a floatable band at the lower part of the jacket, including a wood core and a spring actuated clamp,

membersextending from the bands to secure same together, a helmet, aflexible accordionlike neck portion connectingithelhelmet to the jacket, and breathing means extending from the helmet and automatically operated to close the helmet against admission of water when in use or when the wearer tilts the ball valve located in each open work chamher adapted to cooperate with the seats to close the admission of water to the housing when the helmet. is tilted, a mouth opening formed inthe front of the helmet, and a door closing the mouth openin ABnAi-iAMiaAmvmN.
